Drill Bit Types Wood

The larger bits require a fairly powerful drill to bore deep holes. the bits cause a lot of splintering as they break out the back of the workpiece - using a sacrificial backing board will reduce this. flat wood bits are not really suitable for enlarging an existing hole. sizes range between 8 and 32mm.. Forstner bits are a very specialised drill bit type commonly used for installing concealed hinges (usually 26mm or 35mm in diameter). they are capable of boring large diameter holes in wood, and their flat-bottom design enables users to pull just short of going through the piece of wood.. Drill bits are often classified by the materials from which they are manufactured and the coatings applied to them. high-speed steel (hss) drill bits are used for drilling wood, light metals, fiberglass and pvc.; black oxide-coated drill bits are more durable than standard hss bits and the coating helps the drill bit resist rust. these are best for hardwood, softwood, pvc, fiberglass and steel..
